概要

Description

STM32F051R8T7TR is an STMicroelectronics MCU in the STM32F0 family. It uses an ARM Cortex‑M0 32‑bit core operating up to 48 MHz. It provides 64 KB of Flash program memory and 8 KB of SRAM. Peripherals typically include GPIO, multiple timers, a 12‑bit ADC, and common serial interfaces (USART/UART, SPI, I2C) with DMA support. Power supply range is ~2.0–3.6 V with low‑power sleep modes for energy efficiency. The device is offered in a 48‑pin package (LQFP), with Tape‑and‑Reel packaging denoted by TR. This MCU is suited for cost‑sensitive, small‑footprint embedded apps such as sensing, simple control, and low‑to‑mid complexity peripherals. Development is supported by STM32CubeMX/HAL/LL libraries and standard ARM toolchains (GCC, Keil, IAR) using ST‑LINK for programming/debugging. Check the exact datasheet for USB availability on this variant.
